Q2. Can the installation location of the AD7011-EVA development environment be selected? Top

First, confirm that the installer has actually stopped. We have received reports that installation requires 30 minutes or more. Check the hard disk access lamp or task manager to confirm computer activity.
We have received reports that the installer stops during installation in rare cases. In such a case, force exit the installer and restart it. Task Manager in Windows can be used to force exit the installer.
After restarting the installer, the check boxes of already installed components may be cleared. However, do not change the component check box settings.

Applicable versions: 01.00.00, 002, and 003

Q4. I build models and programs on another computer. Is it OK to install only AD-VirtualConsole on the computer connected to the AD7011-EVA? Top

Always install the AD7011-EVA development environment before installing the AD-VirtualConsole. This is necessary because the AD-VirtualConsole requires some of the software components included in the AD7011-EVA development environment.

Applicable versions: 01.00.00, 002, and 003

Variable Steps:

Q1. Can the AD7011-EVA run variable step models of the solver option of Simulink? Top

No, it cannot. However, the AD7011-EVA can run fixed step models.

Applicable versions: 01.00.00, 002, and 003

The Project Selection Screen:

Q1. How do I display the project selection screen after the AD7011-EVA starts? Top

Create a GUI screen in VCDesigner and then paste a system operation button (set the command to “Exit”) on the screen. If the system operation button is used when a project is starting on the AD7011-EVA, the project is exited and the project selection screen appears.

Applicable versions: 01.00.00, 002, and 003

Q2. Is it possible for a specified project to start automatically when the AD7011-EVA is started? Top

Start the desired project from VCDesigner. When the AD7011-EVA is started, the project last started in VCDesigner automatically starts.

Applicable versions: 01.00.00, 002, and 003

Q3. How do I display the project selection screen when the AD7011-EVA is starting? Top

First, switch on the AD7011-EVA power. While “Starting up system…” is displayed, touch and hold the touchpanel in any two locations. The project selection screen soon appears.

You can confirm in detail whether programs made with eclipse run as expected on the AD7011-EVA.
Programs made with eclipse can be debugged via a telnet connection over Ethernet. Program operations can be checked by running program code line by line or by running programs up to a specified break point in the code.
For details, see the instruction manual (AD7011-EVA application development guide.pdf).

With MATLAB/Simulink models, data can be saved using the DataStore and BlockDataStore blocks of the A&D AD-XPRTS System Blockset library.
With C language programming, there are sample programs on the DVD that use functions for data saving from version 002.
In all cases, the file destination is set using AD-VirtualConsole.

Applicable versions: 01.00.00, 002, and 003

Q2. Can SD cards and USB memory be used to save data on the AD7011-EVA? Top

The microSD card on the AD7011 cannot store large amounts of data because it contains realtime modules, AD-VirtualConsole GUI screen files, applications, and other data.
However, large amounts of data can be stored using SD cards and USB memory.
The maximum capacity of cards and memory is determined by its file system format. If storage media is formatted as FAT32, data can be read and written on both the AD7011-EVA and a personal computer.
The reading and writing speed are determined by the type of SD card or USB memory used.

The serial console uses UART1.
For details, see the AD7011-EVA environment configuration guide.

Applicable versions: 01.00.00, 002, and 003

Sampling Cycle:

Q1. How fast can the sampling cycles (program execution cycles and model cycles) on the AD7011-EVA be set? Top

The cycle depends on the model or program. However, a rough standard is 1 ms (1 kHz). At this level, a wide range of systems can be created.

Applicable versions: 01.00.00, 002, and 003

Cables and Terminal Blocks:

Q1. Tell me about the cables and terminal blocks for the 96-pin connector of the AD7011-EVA. Top

The following specifications are accurate as of January 20, 2010.
Cables: Misumi WPCR-SS-96-0.5 or equivalent
Terminal block: Misumi MWI-PCR96-TB96 or equivalent

The files required to create a cross compiler environment are on the DVD included with the AD7011-EVA. For the procedure to create a Linux host environment, see the AD7011-EVA environment creation guide on the included DVD. A&D has no record in creating environments on other operating systems.

Applicable versions: 01.00.00, 002, and 003

Ethernet:

Q1. What is the supported transfer speed of the Ethernet port of the AD7011-EVA? Top

The watchdog function is performed by the CPLD of the AD7011.The block diagram of the AD7011-EVA in the catalog shows mainly the connection of the AD7011 and AD7011-EVA, and therefore the watchdog function is not listed. However, the 2-pin header of the J45 or the 19th pin of 96-pin connector can be used.

Applicable versions: 01.00.00, 002, and 003

USB Hubs:

Q1. The AD7011-EVA has only one standard USB connector. Is there a way to increase the number of connections? / Q2. Can USB hubs be used with the AD7011-EVA? Top

The AD7011-EVA has a single Type-A USB connector. To connect multiple USB peripherals, use a USB hub. However, do not connect multiple USB memory devices.

Q1. Is the LAN cable that directly connects the AD7011-EVA and a personal computer a cross cable? Can a straight cable be used? Top

JTAG is a method for inspecting IC chips and debugging programs. Specifications are standardized and many IC chips support JTAG. Due to these factors, a JTAG environment makes it possible to inspect and debug many IC chips.
Further details are beyond the scope of this FAQ but there is a large amount of information on JTAG available on the Internet and in other places.

I2C is a serial bus developed by Philips. They are used in systems that focus on cost over communication speed since networks can be configured with two wires.
They are used in embedded systems, mobile phones, consumer electronics, and other devices.
Further details are beyond the scope of this FAQ but there is a large amount of information on I2C available on the Internet and in other places.

Q1. What is EEPROM on the AD7011-EVA? / Q2. Can users freely use the EEPROM of the AD7011-EVA? Top

CSPI stands for Configurable Serial Peripheral Interface. This synchronous serial communication that can have its settings changed by a program.
On the AD7011-EVA, it is used for connections to AD (4 channel), DA (4 channel), and ZigBee (optional).
One feature of the CSPI is that it can be directly controlled from the i.MX31 CPU.

Applicable versions: 01.00.00, 002, and 003

Q2. What is the difference between the CSPI AD/DA and expansion bus AD/DA? Top

The CSPI AD/DA has a slow bus speed and cannot guarantee real-time performance for software.
Expansion bus AD/DA is premised on real-time performance. Therefore, the hardware bus is also designed based on this premise, as is the software implementation.

1-Wire is a trademark of Maxim Integrated Products. While the communication speed is slow, this low-cost device is used as a bus specification that connects with only two wires.
For example, 1-Wire is used in situations where data is transmitted via quick contact, such as with warning devices and hotel door keys.
Further details are beyond the scope of this FAQ but there is large amount of information data on 1-Wire available on the Internet and in other places.
